During the interview Maddow described the difference between
MSNBC and Fox thusly:

"I of course think [MSNBC] is much more true than Fox is
true. The problem that is reasonable to assert about Fox
and its coverage is that they make up stories for their own
purpose...For example, they said the New Black Panther
Party decided the election for Barack Obama. They ran
dozens and dozens and dozens of stories about the New Black
Panther Party, which was one guy who braided his beard in
Philadelphia and who didn’t have an organization, yelling on a
street corner. They represented that story as if that is the guy
who decided the election. That was fake."

This apparently perked up the ears of Politifact, who has seen a
serious surge of popularity since Jake Tapper began employing it to fisk
his guests on This Week.

Turns out that while "there was indeed lots of coverage on
Fox...the discussions focused on the legal side of the story and
whether other media outlets were derelict in not giving it enough
attention." And no one actually said "the New Black Panther
Party decided the election for Barack Obama."
